Struct GcGradientCheckpoint 

pub struct GcGradientCheckpoint {
    pub id: CheckpointId,
    pub step: u64,
    pub gradients: HashMap<String, GcGradientTensor>,
    pub created_at: u64,
    pub compressed_size: usize,
    pub checksum: u64,
}

A snapshot of accumulated and (optionally clipped) gradients at a particular training step.

Fields

id: CheckpointId

Unique identifier for this checkpoint.

step: u64

The global step counter at the time flush was called.

gradients: HashMap<String, GcGradientTensor>

Per-layer gradient tensors after accumulation and clipping.

created_at: u64

Wall-clock timestamp (seconds since Unix epoch) at creation time, supplied by the caller of flush.

compressed_size: usize

Approximate compressed size (in bytes) of the serialised gradient data. Currently approximated as 8 * total_values.

checksum: u64

FNV-1a hash over all gradient values (layer order sorted by layer_id).
